What is the difference between a data warehouse and a database? Please two major differences clearly. What are the similarities between a data warehouse and a database? Please two key similarities clearly. (1.5 Marks)

Answers

Answer 1

A data warehouse and a database are both used to store and manage data, but they serve different purposes and have distinct characteristics. Two major differences between a data warehouse and a database are their design and data structure.

1. Purpose and Design: A database is designed to support the day-to-day transactional operations of an organization. It is optimized for efficient data insertion, retrieval, and modification. On the other hand, a data warehouse is designed to support decision-making and analysis processes. It consolidates data from multiple sources, integrates and organizes it into a unified schema, and optimizes it for complex queries and data analysis.

2. Data Structure: Databases typically use a normalized data structure, where data is organized into multiple related tables to minimize redundancy and ensure data consistency. In contrast, data warehouses often adopt a denormalized or dimensional data structure. This means that data is organized into a structure that supports analytical queries, such as star or snowflake schema, with pre-aggregated data and optimized for querying large volumes of data. Despite their differences, there are also key similarities between data warehouses and databases:

1. Data Storage: Both data warehouses and databases store data persistently on disk or other storage media. They provide mechanisms to ensure data integrity, durability, and security.

2. Querying Capabilities: Both data warehouses and databases offer query languages (e.g., SQL) that allow users to retrieve and manipulate data. They provide mechanisms for filtering, sorting, aggregating, and joining data to support data analysis and reporting. While databases and data warehouses have distinct purposes and structures, they are complementary components of an organization's data management infrastructure. Databases handle transactional processing and real-time data storage, while data warehouses focus on providing a consolidated and optimized data repository for analytical processing and decision-making.

A lake with a surface area of 525 acres was monitored over a period of time. During onemonth period the inflow was 30 cfs (ie. ft3 /sec), the outflow was 27 cfs, and a 1.5 in seepage loss was measured. During the same month, the total precipitation was 4.25 inches. Evaporation loss was estimated as 6 inches. Estimate the storage change for this lake during the month.

Answers

Answer:

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

Explanation:

We must estimate the monthly storage change of the lake by considering inflows, outflows, seepage and evaporation losses and precipitation. That is:

\(\Delta V_{storage} = V_{inflow} -V_{outflow}-V_{seepage}-V_{evaporation}+V_{precipitation}\)

Where \(\Delta V_{storage}\) is the monthly storage change of the lake, measured in cubic feet.

Monthly inflow

\(V_{inflow} = \left(30\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{inflow} = 77.76\times 10^{6}\,ft^{3}\)

Monthly outflow

\(V_{outflow} = \left(27\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{outflow} = 66.98\times 10^{6}\,ft^{3}\)

Seepage losses

\(V_{seepage} = s_{seepage}\cdot A_{lake}\)

Where:

\(s_{seepage}\) - Seepage length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{seepage} = 1.5\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{seepage} = (1.5\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{seepage} = 2.86\times 10^{6}\,ft^{3}\)

Evaporation losses

\(V_{evaporation} = s_{evaporation}\cdot A_{lake}\)

Where:

\(s_{evaporation}\) - Evaporation length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{evaporation} = 6\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{evaporation} = (6\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{evaporation} = 11.44\times 10^{6}\,ft^{3}\)

Precipitation

\(V_{precipitation} = s_{precipitation}\cdot A_{lake}\)

Where:

\(s_{precipitation}\) - Precipitation length gain, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{precipitation} = 4.25\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{precipitation} = (4.25\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{precipitation} = 8.10\times 10^{6}\,ft^{3}\)

Finally, we estimate the storage change of the lake during the month:

\(\Delta V_{storage} = 77.76\times 10^{6}\,ft^{3}-66.98\times 10^{6}\,ft^{3}-2.86\times 10^{6}\,ft^{3}-11.44\times 10^{6}\,ft^{3}+8.10\times 10^{6}\,ft^{3}\)

\(\Delta V_{storage} = 4.58\times 10^{6}\,ft^{3}\)

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

The volume of water gained and the loss of water through flow,

seepage, precipitation and evaporation gives the storage change.

Response:

The storage change for the lake in a month is 1,582,823.123 ft.³

How can the given information be used to calculate the storage change?

Given parameters:

Area of the lake = 525 acres

Inflow = 30 ft.³/s

Outflow = 27 ft.³/s

Seepage loss = 1.5 in. = 0.125 ft.

Total precipitation = 4.25 inches

Evaporator loss = 6 inches

Number of seconds in a month is found as follows;

\(30 \ days/month \times \dfrac{24 \ hours }{day} \times \dfrac{60 \, minutes}{Hour} \times \dfrac{60 \, seconds}{Minute} = 2592000 \, seconds\)

Number of seconds in a month = 2592000 s.

Volume change due to flow, \(V_{fl}\) = (30 ft.³/s - 27 ft.³/s) × 2592000 s = 7776000 ft.³

1 acre = 43560 ft.²

Therefore;

525 acres = 525 × 43560 ft.² =  2.2869 × 10⁷ ft.²

Volume of water in seepage loss, \(V_s\) = 0.125 ft. × 2.2869 × 10⁷ ft.² = 2,858,625 ft.³

Volume gained due to precipitation, \(V_p\) = 0.354167 ft. × 2.2869 × 10⁷ ft.² = 8,099,445.123 ft.³

Volume evaporation loss, \(V_e\) = 0.5 ft. × 2.2869 × 10⁷ ft.² = 11,434,500 ft.³

\(Storage \, change \, \Delta V = \mathbf{V_{fl} - V_s + V_p - V_e}\)

Which gives;

ΔV = 7776000 - 2858625 + 8099445.123 - 11434500 = 1582823.123

The storage change, ΔV = 1,582,823.123 ft.³

hw2.3: consider a power transistor encapsulated in an aluminum case that is attached at its base to a square aluminum plate of thermal conductivity k

Answers

The aluminum case of a power transistor that is attached to a square aluminum plate of thermal conductivity k is considered in this problem. A power transistor is a type of transistor that is designed to handle high power levels,

Making it suitable for use in power amplifiers, voltage regulators, and other applications that require high currents and voltages.The thermal conductivity of a material is a measure of how well it conducts heat. The higher the thermal conductivity of a material, the better it is at transferring heat from one place to another. Aluminum is a good conductor of heat, with a thermal conductivity of around 200 W/m·K.

This means that it can transfer heat quickly and efficiently from the transistor to the plate.The problem asks us to consider the heat transfer from the transistor to the plate, and to determine the temperature rise of the transistor as a result.

We can use the following equation to calculate the temperature rise:

ΔT = P * Rθ

where ΔT is the temperature rise in degrees Celsius, P is the power dissipated by the transistor in watts, and Rθ is the thermal resistance from the transistor to the plate in degrees Celsius per watt.

The thermal resistance can be calculated using the following equation:

Rθ = t/kA

where t is the thickness of the aluminum case, k is the thermal conductivity of aluminum, and A is the surface area of the aluminum case. We can assume that the thickness of the case is uniform and that the surface area is equal to the area of the base of the case, since this is where the case is attached to the plate.

The power dissipated by the transistor can be calculated using the following equation:

P = VCE * IC

where VCE is the voltage across the collector and emitter terminals of the transistor, and IC is the current flowing through the collector terminal. We can assume that the voltage and current are constant, since the transistor is designed to operate at a specific voltage and current level.

To calculate the temperature rise of the transistor, we need to determine the values of P and Rθ, and then substitute them into the equation for ΔT. We can then solve for ΔT to obtain the temperature rise in degrees Celsius.

Explain the difference between dimensioning standards for inches and the standards for millimeters

Answers

Dimensioning standards for inches and millimeters are used to specify the size and location of features on an object or part. The primary difference between these two standards is the unit of measurement used.

Inches are the primary unit of measurement in the United States, and dimensioning standards for inches are based on the imperial system of measurement. This system is based on units of inches, feet, and yards.

Dimensioning standards for inches typically use fractions of an inch, such as 1/8", 1/16", or 1/32", to specify dimensions. These fractions are commonly used because they are easy to measure with common tools like rulers and calipers.

On the other hand, millimeters are the primary unit of measurement in most other parts of the world, and dimensioning standards for millimeters are based on the metric system of measurement. This system is based on units of millimeters, centimeters, and meters.

Dimensioning standards for millimeters typically use decimals, such as 1.5 mm or 3.75 mm, to specify dimensions. Decimals are commonly used in the metric system because they allow for more precise measurements and are easier to work with in mathematical calculations.

Determine the normal stress and shear stress acting on the inclined plane ab. Solve the problem using the stress transformation equations. Suppose that τ = 5. 5 ksi

Answers

The normal stress on the inclined plane ab is σ = 2.0625 ksi and the shear stress on the inclined plane ab is τ = 1.375 ksi.

How did we get the values?

Determining the normal stress and shear stress acting on the inclined plane ab, use the stress transformation equations.

The stress transformation equations relate the normal stress, σ, and shear stress, τ, on an inclined plane with the corresponding normal and shear stresses acting on a plane perpendicular to the inclined plane. The equations are:

σ = σn cos²θ + σs sin²θ ± 2τnsinθcosθ

τ = (σn - σs) sinθcosθ ± τn cos²θ ± τs sin²θ

where θ is the angle between the inclined plane and the plane of reference, σn and σs are the normal stresses acting on the plane of reference, τn and τs are the shear stresses acting on the plane of reference, and τns is the shear stress acting on the inclined plane.

Given that τ = 5.5 ksi and σ and τ are to be determined on the inclined plane ab. Assume a plane of reference perpendicular to the inclined plane ab with angle θ in between.

The angle θ between the inclined plane and the plane of reference is the complement of the angle of inclination, so θ = 90° - 30° = 60°.

Assuming that there are no normal stresses acting on the plane of reference, so σn = 0. Therefore, the stress transformation equations simplify to:

σ = σs sin²θ ± 2τnsinθcosθ

τ = (σs/2) ± τn cos²θ ± (τ/2)sin²θ

Solve for σs and τn by using the given value of τ and the fact that there are no normal stresses acting on the plane of reference:

τ = τns = 5.5 ksi

σs = τ/2 = 2.75 ksi

τn = 0

Substitute these values into the stress transformation equations to obtain the normal stress and shear stress on the inclined plane ab:

σ = σs sin²θ = 2.75 ksi sin²60° = 2.75 ksi (0.75) = 2.0625 ksi

τ = (σs/2) ± τn cos²θ ± (τ/2)sin²θ = 2.75 ksi/2 = 1.375 ksi

Therefore, the normal stress on the inclined plane ab is σ = 2.0625 ksi and the shear stress on the inclined plane ab is τ = 1.375 ksi.

determine the steady state temperature distribution between two concentric spheres with radii 1 and 4

Answers

Answer:

Hence, the steady state temperature distribution between concentric spheres with radii 1 and 4 is:

u = \(\frac{C1}{r }\) + C2

u = \(\frac{\frac{-320}{3} }{r}\) + \(\frac{320}{3}\)

Explanation:

Solution:

Note: This question is incomplete and lacks necessary data to solve this question. But I have found a similar question and will try to solve it.

This question has this following part missing:

"If the temperature of the outer sphere is maintained at 80 degrees and the inner sphere at 0 degrees.

Now, this question is complete.

Let's find out the steady state temperature distribution.

As, we know the spherical symmetric heat equation:

\(\frac{du}{dt}\) = \(\frac{k}{r^{2} }\) \(\frac{D}{Dr}\) (\(r^{2}\) \(\frac{Du}{Dr}\))

Where, small (d) represents the partial differentiation and Capital D represents simple derivative.

And the ordinary differential equation (ODE) for steady state temperature distribution is:

\(\frac{k}{r^{2} }\) \(\frac{D}{Dr}\)(\(r^{2}\) \(\frac{Du}{Dr}\)) = 0

So it can be said that:

\(r^{2}\) \(\frac{Du}{Dr}\)

Consequently,

\(\frac{Du}{Dr}\) = \(\frac{C1}{r^{2} }\)

Taking derivative of the above equation we get:

u = -\(\frac{C1}{r }\) + C2

Solution of the ordinary differential equation

u = \(\frac{C1}{r }\) + C2 (Consuming the negative sign into C1 constant)

As, it is given in our question that our boundary conditions are: 1 and 4

So,

Putting the boundary conditions into the variable (r) to find the constants we get:

u1 = \(\frac{C1}{1} }\) + C2 = 0 (degrees)

u1 = C1 + C2 = 0 (degrees)  equation (1)

Similarly,

u4 = \(\frac{C1}{4}\) + C2 = 80 (degrees)

u4 = \(\frac{C1}{4}\) + C2 = 80 (degrees)  equation (2)

Solving for C1, we get:

Equation 1 - Equation 2

(C1 - C2 = 0) - (\(\frac{C1}{4}\) + C2 = 80)

\(\frac{-3}{4}\)C1 = 80

Solving for C1

C1 = -\(\frac{320}{3}\)

With the help of value of C1, we get value of C2

Put the value of C1 in equation (1) to get value of C2

C1 + C2 = 0

-\(\frac{320}{3}\) + C2 = 0

Solving for C2

C2 = \(\frac{320}{3}\)

Hence, the steady state temperature distribution between concentric spheres with radii 1 and 4 is:

u = \(\frac{C1}{r }\) + C2

Plugging in the values of C1 and C2

u = \(\frac{\frac{-320}{3} }{r}\) + \(\frac{320}{3}\)

D=0.3 m±0.01 m L=150 m±0.1 m Calculate the derivatives numerically.

Answers

The flowrate Q is estimated to be 10.83 m³/s, and the uncertainty is 0.64 m³/s (i.e., 5.89%).

To estimate the uncertainty in the flowrate for the measured values: Q = 128μL ΔPπD / 4.

Where ΔP = 12kN/m² ± 0.3kN/m²; D = 0.3m ± 0.01 m,

L = 150m ± 0.1m and μ = 0.001 kg/m-s (the dynamic viscosity of water).

The formula for the uncertainty of flowrate using the given parameters can be calculated as follows:

ΔQ/Q = ΔΔP/ΔP + ΔD/D + ΔL/L Since ΔP = 12kN/m² ± 0.3kN/m²,

The percentage uncertainty in ΔP is given as follows: (0.3kN/m²/12kN/m²) × 100% = 2.5%

Similarly, the percentage uncertainty for D and L can be computed as follows:

ΔD/D = (0.01m/0.3m) × 100% = 3.33%ΔL/L = (0.1m/150m) × 100% = 0.067%

The flowrate Q can be calculated as follows: Q = 128μL ΔPπD / 4Q = 128 x 0.001 x 150 x (12/4) x 3.1416 x (0.3) ⁴ = 10.83 m³/s

The uncertainty in Q can be calculated as follows:

ΔQ/Q = ΔΔP/ΔP + ΔD/D + ΔL/LΔQ/Q = 2.5% + 3.33% + 0.067%ΔQ/Q = 5.89%

Therefore, the flowrate uncertainty is ΔQ = (5.89/100) x 10.83 = 0.64 m³/s.

The volumetric flowrate formula in a horizontal pipe for laminar flow is Q = 128 μL ΔPπD / 4.

The flowrate uncertainty can be calculated using the formula, ΔQ/Q = ΔΔP/ΔP + ΔD/D + ΔL/L.

The values of ΔP, D, and L are ΔP = 12k N/m ² ± 0.3k N/m ², D = 0.3m ± 0.01 m, and L = 150m ± 0.1m,

Therefore, the flowrate Q is estimated to be 10.83 m³/s, and the uncertainty is 0.64 m³/s (i.e., 5.89%).

determine the circulation for the given vector field around the enclosed half circle of radius 1.

Answers

To determine the circulation for the given vector field around the enclosed half circle of radius 1, we need to calculate the line integral of the vector field along the boundary of the half circle.

The line integral is calculated by integrating the dot product of the vector field and the differential of the boundary. The circulation is then equal to the line integral divided by . To calculate the line integral, we need to know the vector field and the boundary of the half circle. Once we have this information, we can use the equation for the line integral to calculate the circulation.

The line integral is calculated by integrating the dot product of the vector field and the differential of the boundary. The differential of the boundary is equal to the vector from the starting point to the end point of the boundary. The vector field can be expressed as a function of the coordinates of the boundary. Once we have the vector field and the differential of the boundary, we can use the equation for the line integral to calculate the circulation. The circulation is then equal to the line integral divided by 2π.

A high molecular weight hydrocarbon gas A is fed continuously into a heated mixed flow reactor (0.1liter) where it is thermally cracked into lower molecular weight materials collectively called R as the reaction stoichiometry A 5R. Find the space velocity if molar feed rate was 300millimol/ hr and the feed concentration was 100millimol / lit.

Answers

Answer:

Space velocity = 30 hr⁻¹

Explanation:

Space velocity for reactors express how much reactor volume of feed or reactants can be treated per unit time. For example, a space velocity of 3 hr⁻¹ means the reactor can process 3 times its volume per hour.

It is given mathematically as

Space velocity = (volumetric flow rate of the reactants)/(the reactor volume)

Volumetric flowrate of the reeactants

= (molar flow rate)/(concentration)

Molar flowrate of the reactants = 300 millimol/hr

Concentration of the reactants = 100 millimol/liter

Volumetric flowrate of the reactants = (300/100) = 3 liters/hr

Reactor volume = 0.1 liter

Space velocity = (3/0.1) = 30 /hr = 30 hr⁻¹

when the power rating of a transformer is exceeded by placing too great on the transformer, the voltage will start to

Answers

When the power rating of a transformer is exceeded by placing too great on the transformer, the voltage will start to drop, and the transformer may overheat and be damaged.

This is because exceeding the power rating causes the transformer to draw more current than it is designed to handle, resulting in increased losses due to the resistance of the winding and core materials. This increased current also causes a voltage drop across the winding and leads to a decrease in output voltage, which can cause problems downstream in the circuit. If the current continues to increase beyond the transformer's capacity, it can cause overheating and damage to the winding insulation, leading to short circuits and potential safety hazards.

A scale on a blue print drawing of a house shows that 666 centimeters represents 333 meters.
What number of centimeters on the blue print represents an actual distance of 272727 meters?

Answers

Answer:

545454cm

Explanation:

The blue print drawing of the house shows 666 centimeters, but the real picture of the house is 333 meters. So let the number of cm on the blueprint that represent the distance of 272727 meters be x. Firstly convert the meters to centimeters 666cm = 333m, x=272727m ; then cross multiply, 666cm=33300cm x=27272700cm ; x =(666cm×272727cm)/33300cm =545454cm.
